Jean-Mary tutored a group of linebackers in 2010 that were one of the most consistent units on the football team. Led by Brandon Heath, the linebackers finished as three of the team's top six tacklers. Heath registered 70 tackles and three sacks, while Daniel Brown had 54 tackles and three sacks.

Jean-Mary (pronounced JON-muh-REE), who was at the University of Louisville in 2000, was instrumental in building a Georgia Tech defense that was one of the most consistent units in the country. He helped coach a Georgia Tech unit that has been ranked among the nation's Top 30 in rushing defense, total defense and scoring defense in five of the six seasons.

Under Jean-Mary's tutelage, Yellow Jacket linebackers Phillip Wheeler and Gary Guyton became the core of the Tech defense in 2008. The duo were first and second on the team in tackles, respectively, and combined for 22.5 tackles-for-loss and 11 sacks in 2007. Wheeler was once again awarded for his play by being selected to the All-ACC second team. As a team, Tech led the nation in sacks and ranked second in tackles-for-loss during the regular season.

Jean-Mary tutored the linebacker duo of KaMichael Hall and Wheeler into two of the top defenders in the Atlantic Coast Conference in 2006. Wheeler earned second-team All-America honors as well as second-team All-ACC accolades, while Hall garnered honorable mention All-ACC recognition.

In 2005, Jean-Mary coached two-time All-Atlantic Coast Conference linebacker Gerris Wilkinson, Tech's leading tackler his last two seasons. Wilkinson was a third-round draft pick of the New York Giants. Jean-Mary's linebackers recorded seven of the Yellow Jackets' 21 interceptions.

In 2004,Jean-Mary also worked with Chris Reis, who earned Honorable Mention All-ACC honors in his only season at outside linebacker. Wilkinson and Reis flourished at linebacker after moving from defensive end and safety, respectively.

Prior to his tenure at Georgia Tech, Jean-Mary spent one season coaching the defensive backs at North Alabama, one of the top programs in NCAA Division II.
He helped the Lions to a 13-1 record, the Gulf South Conference title and a berth in the semifinals of the NCAA Division II playoffs in 2003. North Alabama's defense was one of the best in the nation, ranking sixth nationally in scoring defense at 14.1 points per game, and 25th in pass defense and 26th in total defense.

Jean-Mary previously spent two years (2001-02) as a defensive graduate assistant at South Carolina under Lou Holtz and one year (2000) as a graduate assistant on the strength and conditioning staff at Louisville.

A native of Apopka, Fla., Jean-Mary played college football at Appalachian State, where he earned a bachelor's degree in 1998.

Jean-Mary is married to the former Jerilyn Ardis and has two children: Brooke and Brittany.
